Leners Patent No. 96,320, zat-z November 2,1869. I

IMPRovnMNT m Looms.

The Schedule :sieri-e6 to in these Letters Patent 'and making part ofthe same.,`

Be it known that I, JOHN'G. HENDERSON, of

Keokuk, in the county of Lee, and State. of Iowa,

have invented a new and useful Improvement in Hand- Looms; and I do hereby declare that the following is a full,. clear, and exact description of the construction and operation of the'same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view.

Figure 2 is a view of a device for thl'owing the shuttle.

Figure 3 is a view of the mode of attaching the shafts to the jacks.

The frame is constructed of four side-pieces, A A A A, iig. I.1, made all the same shape.

A hole is made in the centre of each, through which the round tenen of the tie B passes, which vholds the frame together.

The supports D D are halved on and bolted to the side-pieces, and hold them the proper distance apart,A

without the side-pieces being gained into each other.l

The 'cam-wheel a', iig. 1, is `rolled partly around at each forward motion ofthe lay by the dog x, which is worked by the rod b, which is pivoted to the lever c, which is attached to 4the lower part of the lay d.

The pins in fthe cam-wheel operate the jacks e e, which, being attached to the harness-shafts, make the upper shed.

A cord passes from the pulley g, around the pulley 7|, on the lever c, to the pulley f.

A cord passes from the irst shaft around the pulley.

g to the second shaft, and a cord passes from the third shaft around the pulley f to the fourth shaft, so that when one or moreof the shafts are held up, the rest are drawn down as the lay goes backward, completing the shed.

The shuttle is thrown by straps attached toblocks,

in the usual manner, and to the' picker-stati` i, fig. 2, all k. l

This picker-steli is pivoted in a mortise in the lay,

o, fig. 2, through which a strap, n, fig. 2, passes, which is attached at one end-to the breast-beam E, fig. 1, as seen at n, fig. 1, and at the other to the arrowshaped iro'n m, fig. 2.

As the lay goes backward, the iron m engages the end of the staple o that is farthest back, throws the picker-stati` around, and, as the lay goes back the next time, engages the other end, throwing the shuttle back and forth, as required.

On one end of the cordfr, iig. 3, a loop is formed, as seen at u. k

The other end is then passed through thev jack, a part of which is' shown at e, iig. 3,1a'nd is returned and passed around the harness-shaft s,lg. 3, then v through the loop u, and tied tothe shaft s.V

When it is required to-make the shed higher, the operator has 'only to draw the loop u toward the jack e, as far as desired, and it will remain where it is put, thus making the change without tying the strings.

What I claim as my invention, and desire to secure by Letters Patent, isy 1. The pattern-cylinder, placed on the top of the loom-jacks e e, rod b, pulleys f g h, and connectingcords, and the level' o, all combined and arranged as shown, to form the shed.

2. 'IheA arrangement, with the jcksand. harnessframes, of the looped cord r u, to adjust the position of the harness, to form a small orlarge shed without untying the strings, as described.

, JOHN G. HENDERSON.
